Boa's `Context::eval()` and `Context::parse()` functions allow reading a byte slice directly, apart from a string. We were not showing this properly in our examples, so this modifies the `loadfile.rs` example to use a byte vector instead of a string, which allows us to use UTF-16 files, if I'm not mistaken.
This is an experiment that tries to migrate the codebase from eager `Error` objects to lazy ones.
In short words, this redefines `JsResult = Result<JsValue, JsError>`, where `JsError` is a brand new type that stores only the essential part of an error type, and only transforms those errors to `JsObject`s on demand (when having to pass them as arguments to functions or store them inside async/generators).
This change is pretty big, because it unblocks a LOT of code from having to take a `&mut Context` on each call. It also paves the road for possibly making `JsError` a proper variant of `JsValue`, which can be a pretty big optimization for try/catch.
A downside of this is that it exposes some brand new error types to our public API. However, we can now implement `Error` on `JsError`, making our `JsResult` type a bit more inline with Rust's best practices.
~Will mark this as draft, since it's missing some documentation and a lot of examples, but~ it's pretty much feature complete. As always, any comments about the design are very much appreciated!
Note: Since there are a lot of changes which are essentially just rewriting `context.throw` to `JsNativeError::%type%`, I'll leave an "index" of the most important changes here:

This Pull Request is related to #2098.
It changes the following:
- Implements `JsRegExp`
- Adds a brief `JsRegExp` example under `boa_examples`
I think it's time to address the elephant in the room.
This Pull Request will (hopefully!) solve part of #736.
This is a complete rewrite of `JsString`, but instead of storing `u8` bytes it stores `u16` words. The `encode!` macro (renamed to `utf16!` for simplicity) from the `const-utf16` crate allows us to create UTF-16 encoded arrays at compilation time. `JsString` implements `Deref<Target=[u16]>` to unlock the slice methods and possibly make some manipulations easier. However, we would need to create our own library of utilities for `JsString`.
This Pull Request closes#2080.
It moves all implementors of the `JsObjectType` trait into their own `js_object` module.
This should simplify documentation and by doing a `pub(crate)` export in `object` little to no imports within the crate need to be changed, simplifying the usage of this module within the boa_engine crate.
Documentation within the `object` module has been updated to reflect this change and in a way that it is shown on the home page of the documentation.

This Pull Request is related to #2098 .
It changes the following:
- Implements a wrapper for `DataView`
- Adds an example of `JsDataView` to the `JsArrayBuffer` example file under boa_examples
Co-authored-by: jedel1043 <jedel0124@gmail.com>
This Pull Request switches our codebase to the brand new [workspace inherited keys](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-package-table), which allows us to define common package options that are usable within each crate's Cargo.toml file.
It also allows to share dependency versions between crates, but I defined only shared versions for our workspace members. It would be a good follow-up to lift all the shared dependencies between crates into the global Cargo.toml.
This PR adds the `ArrayBuffer` rust wrapper. It also provides a capability to construct a `JsArrayBuffer` from a user defined blob of data ( `Vec<u8>` ) and it is not cloned, it is directly used as the internal buffer.
This allows us to replace the inifficent `Vec<u8>` to `JsArray` then to `TypedArray` (in typed arrays `from_iter`), with a `JsArrayBuffer` created from user data to `TypedArray`. With this `Vec<u8>` to `JsTypedArray` should be fully fixed as discussed in #2058.
This PR adds a safe wrapper around JavaScript `JsSet` from `builtins::set`, and is being tracked at #2098.
Implements following methods
- [x] `Set.prototype.size`
- [x] `Set.prototype.add(value)`
- [x] `Set.prototype.clear()`
- [x] `Set.prototype.delete(value)`
- [x] `Set.prototype.has(value)`
- [x] `Set.prototype.forEach(callbackFn[, thisArg])`
Implement wrapper for `builtins::set_iterator`, to be used by following.
- [x] `Set.prototype.values()`
- [x] `Set.prototype.keys()`
- [x] `Set.prototype.entries()`
*Note: Are there any other functions that should be added?
Also adds `set_create()` and made `get_size()` public in `builtins::set`.

This Pull Request related to JsMap for #2098.
Any feedback on implementing JsMapIterator would be welcome. I wasn't entirely sure if it was the right approach, but as I worked on the example file, it felt like something at least similar would be needed to use Map's .entries(), .keys(), and .values() methods.
It changes the following:
- Implements JsMap Wrapper
- Implements JsMapIterator Wrapper
- Creates JsMap example in boa_examples
This adds cargo-workspaces to our repo for easier publishing.
(I think we may need to do a dry run of this first to test)
fixes https://github.com/boa-dev/boa/issues/2001
This Pull Request supersedes #2018 and #2017.
It changes the following:
- Updates the wasm-bindgen dependency now that a new version without the clippy bug has been released
- Updates all dependencies to their latest versions
Added boa examples as per issue #446
Overtaken https://github.com/boa-dev/boa/pull/634
Somehow screwed that branch up by rebasing it and losing access
pings @elasmojs
